Filed: 1946-04-18
Abstract: 611,112. Variable speed gear. HOPKINSON & CO., Ltd., A., and SIDEBOTTOM, T. April 18, 1946, No. 12074. [Class 80 (ii)] [Also in Group XXX] Haulage gear comprises a winch drum 58, Fig. 2, driven by a motor through two sets 1, 11, Fig. 2, of variable reduction gearing arranged on opposite sides of the drum, which drum is mounted to rotate about a stationary hollow shaft 43 through which is passed layshaft 42 for communicating the drive from one set of gears to the other. Clutch and gearing.- Motor 5, Fig. 6, drives inner shaft 9. Driving plates 8b on shaft 9 drive hollow outer shaft 19 through clutch plates 8c. The clutch is operated by a handle which moves tappet ring 13 by means of lever 11a and the tappet ring presses the sliding portion 16 which presses springy pegs 18 to force the two clutch parts together. Hollow shaft 19 is integral with and rotates conical gear 21 which engages with conical gearing 22, Figs. 7, 8. Each gear 22 rotates freely on its shaft and is drivingly connected therewith by means of three angularly spaced pegs 29 which, sliding out against spring 30 fixed within borings in the shaft, engage with pin 32 on each gear 22. A handle 4, Fig. 2, works screw 34 along thread 33, Fig. 8, and the fork part 34a of the screw pushes shaft 31 within hollow shaft 24 so that twin cones 31a engage the pegs 29 and cause the engagement of the selected gear 22 with the corresponding driving gear 21. Accordingly, shaft 24 rotates and causes spur-wheel 36 to rotate. The latter drives spur-wheel 38, Fig. 2, by a chain and the drive passes through bevel gearing 40, 41 to shaft 42 which transfers the drive to the sliding pinion 46 on the other side of the drum, Fig. 10. Handle 46a moves pinion 46 to engage spur-wheel 47 to give a large gear reduction or to engage spur-wheel 48 to give a smaller reduction, and the drive is passed to gear 51 on shaft 49, Fig. 2, to engage internal annular gearing 56 on the drum.

Title: Process for the production of non-knocking benzines
IPC: C10G35/06
Filed: 1934-04-24
Abstract: Knocking, stable, and impure benzines are converted into non-knocking and pure products by treatment in the vapour phase with hydrogen under the following conditions:--(1) a partial pressure of benzine vapour of 0,5--3 atmospheres; (2) a hydrogen pressure of 30--60 atmospheres; (3) a temperature of 450--525 DEG  C., usually of 460--500 DEG  C., and (4) in the presence of catalysts which contain sulphides or oxides of metals of the 5th and/or 6th group of the periodic system, alone or in admixture with sulphides or oxides of heavy-metals of the 1st and/or 8th group, if desired with the addition of non-reducible oxides such as zirconium, thorium or cerium oxide.  With benzines rich in hydrogen, especially such as contain naphthenes, the process is one of dehydrogenation; on the other hand, with benzines poor in hydrogen, hydrogenation also occurs.  Since the first reaction is endothermic, and the second exothermic, it is an advantage for the purpose more easily of maintaining the temperature, to employ mixtures of both types of benzines.  The following are suitable catalysts,--cobalt sulphide, copper sulphide and vanadium sulphide, copper sulphide and tungsten sulphide, copper oxide and molybdenum oxide, nickel sulphide or iron sulphide and tungsten sulphide, nickel sulphide and tungsten sulphide and zirconium oxide or cerium oxide; and the catalyst may be supported on alumina, active carbon or silica, brown coal, small coke, and bleaching earth. Hydrogen or gas mixtures containing hydrogen and nitrogen, carbon monoxide, carbon dioxide, sulphuretted hydrogen, water vapour, methane or other hydrocarbons may be used. Specifications 327,194, [Class 32], and 360,530 are referred to.

Abstract: 658,902. Pneumatic gauging - apparatus. TRIGGS, W. W. (Taft-Peirce Manufacturing Co.). May 13, 1949, No. 12851. [Class 106 (ii)] [Also in Group XXIX] Apparatus for gauging dimensions of bodies by the use of flow of fluid under pressure is characterized in that a fluid stream is passed, via two Venturi tubes of differing diameters and sequentially connected, to a gauging nozzle, wherein the degree of venting through the nozzle is a function of the physical dimension to be determined with respect to a given article placed in operative relationship with the nozzle, and the difference of pressure between the pair of Venturi tubes is measured by a suitable indicator. As shown diagrammatically in Fig. 1, a body 38 is placed over a gauging nozzle 37 supplied with fluid from a source 20 by a pressure regulator 21 from which it passes through a venturi block 26 having two constrictions 31, 32 of different diameter and a bleed valve 30. The two constrictions 31, 32 communicate respectively with the inside of a capsule 47 and a chamber surrounding it and movements of the capsule due to changes in the differential pressure between the two constrictions cause a pin 61 to turn a spindle 59 through a pin 60 which in turn by means of a pin 58 moves a sector 56 meshing with a pinion 55 to actuate a pointer 52 which will then give an indication of the required dimension. In a preferred embodiment, Fig. 3, a suitable gauging head 37 is fitted with a bayonet joint in a socket in a panel 82 of a housing whose front panel 81 is rebated to receive a plate 149 for anchoring the differential pressure gauge 50, Fig. 11, to the back plate 92 of which is fixed the venturi block 26. A rebated recess 88 in the side panel 80 houses control knobs 68, 24 for the bleed valve 30 and pressure regulator, the pressure being shown by a gauge 87 mounted in the top panel. Inlet and outlet plugs 101, 102 in the Venturi block 26 communicate by ducts 25, 36 with the pressure regulator and gauging head respectively and the constrictions 31, 32 communicate with the inside and outside of the capsule 47 through hole 167, Fig. 8, bores 45, 169, 168, chamber 145, Fig. 11, and duct 46 and through hole 170, bore 48, respectively, a restricting sleeve 173, Fig. 8, being provided in the bore 45 to prevent surges of pressure from damaging the capsule. Auxiliary pointers 157, 158, Fig. 9, are provided which may be set through knobs 159, 160 and gear sectors 165, 155 and 164, 156 to indicate tolerances allowable above and below a standard. In operation the apparatus is set by gauging a work-piece of standard size or two pieces at the limits of oversize and undersize tolerance and observing the reading or readings of the pointer 52 on the scale 51. If necessary the reading or range may be centralized by operating the bleed valve 30 through the knob 24 and then the required tolerances may be set by the hand knobs 159, 160.
